Colds, Flu and Immunity: Conventional vs Natural Health

We are constantly surrounded by opportunistic would-be pathogens, fungal, bacterial and viral. Yet, most people, most of the time are not adversely affected by them. We fend off, neutralize or mitigate them thanks to what is referred to as an innate immune system. When a person expresses the constellation of symptoms commonly associated with a cold or flu it appears that a weakened immune system has allowed an aggressive pathogen, a hostile invader,  to proliferate and compromise their health with characteristic results.
Conventional medicine and natural health view and treat cold and flu symptoms in entirely different ways. The conventional approach is to reduce the cold/flu experience to the invasive presence of a specific pathogen against which a synthetic drug or vaccine is prescribed. Regular physicians employ a whack-a-mole strategy. If an apparent cold/flu pathogen pops up  to suppress it with a drug. They don't care or even think about the state of person's immune system.

The natural health approach is to use specific food nutrients and natural health products to supply the immune system with the raw material to restore one a state of normal good health as exists most of the time. Changes in lifestyle, diet, supplements and application of restorative therapies such as acupuncture, chiropractic or exercise are the tools that natural health employs to strengthen your immune system.

Key Foods and Supplements that Strengthen Immunity
There is one critical difference between conventional medicine and natural health as regards immunity. For regular doctors, everybody is the same. Did you get symptoms? Take this drug, get a flu shot. One size fits all. Doesn’t work? See a specialist. Next patient please.
Natural health understands that people are not all the same. For example, constitutionally some people thrive on a vegetarian diet but others require meat to stay healthy. Acid/alkaline, sympathetic/parasympathetic, yin/yang, fast oxidizer/slow oxidizer. There is no universal prescription rather there is an algebra that best suits each individual.
You go to a regular doctor, you don’t have to think. You just do whatever they say. With natural health you have to think, observe, learn, evaluate. You are constantly conducting your own clinical trial in which you are both subject and object. It takes work and you must have a critical disposition. The rewards are a success, enjoyment of life and control of your health. You own your own body. Take responsibility.
What follows are state-of-the-art summaries of key natural health products that have wide application to enhancing immunity with respect to cold and flu symptoms. Don’t take this advice or consume anything blindly. Read up and ask questions.
At Nature’s Source our rule is: bring us your hardest questions.

Vitamin D
Vitamin D is naturally synthesized by exposure of the skin to sunlight. In northern temperate climates like ours this isn’t happening very much so Vitamin D levels are often inadequate. To restore this, supplements are required of which there are two forms: D3, also known as cholecalciferol, and D2, also known as ergocalciferol. The former, produced in the skin on exposure to UVB radiation (290 to 320 nm), is the more bioactive. Both D3 and D2 precursors are converted in the liver and kidneys to storage and biologically active forms.
